I rather liked Ego Draconis. Even though it leaned a little more toward action-adventure than pure RPG, it still had great design, whimsical characters and dialogue, great artwork, and lots of fun.
Flames of Vengeance, on the other hand, should have never been made. If you've never played DKS and you intend to, I strongly recommend skipping the FoV expansion. It's just 20 hours of mind-numbing fetch quests in a town square, many with solutions so obscure that a walkthrough is required to get through the game.
